LAMP-BURN ER.

SPECIFICATION forming part of Letters Patent NO. 524,682, dated Ailg'ust14, 1894.

Application filed February 1 6, 1894. Serial No. 500.377. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH KAMPF, a subject of the German Emperor,residing in the city, county, and State of New York, have inventedcertain newand useful Improvements in Lamp-Burners, of which thefollowing is a specification.

My invention relates to improvements in burners for central-draft lamps;and its object is to provide means whereby the wick may be caused toburn from the exterior and not directly at its upper edge, the samemeans being utilized to entirely close the annular wick-space betweenthe wick-tubes, in which the wick is arranged, so that the wick isprevented from smoking and all the offensive vapors arising therefromafter the light is extinguished prevented.

In the accompanying drawings-Figure 1 is a central sectional view of alamp embodying my improvements. Fig. 2 is a central sectional-view ofthe upper portion of the burner, showing the burner in closed position;and Fig. 3 is a transverse section on line 33, Fig. 1.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents thefount of a central-draftlamp.

B is the flanged burner-base, which is secured into the top of the fountin any suitable manner, B the gallery for supporting the chimney, and Othe foraminous skirt rising from the burner-base B and supporting thegallery, and whereby the burner is supplied with air directly from theexterior, all as customary in such lamps.

The interior wick-tube D of the burner is A secured in the lamp-fountand supplies the air to the interior of the flame, which is evolved fromthe exterior of the wick, as will hereinafter be fully described.Mounted on the upper end of the interior wick-tube D is a suitableannular cap, which comprises a tubular portion d, fitting removably inthe interior wick-tube D, an annular top-portion or ring d, and anexterior depending guardflange d When the wick D is properly insertedover the interior wick-tube D, its top edge abuts against the under sideof the portion or ring (1 of the cap and is confined between theguard-ring d and the body of said wick-tube, said guard-ring therebyprotecting and holding from displacement the raw-edge of the wick.

The exterior wick-tube E is fixed in the burner-base B, and providedbetween itself and the interior wick-tube D with an annular space orchamber, in which the wick is held.

The interior wick-tube extends above the exterior wick-tube so that asufiicient exterior surface of the wick may be left for the attainmentof the desired end. Mounted to slide on the exterior wick-tube E is theflame regulating tube F provided with suitable means for raising andlowering it, and having above the tube E a contracted annular portion fwhich is adapted to move upon the exterior surface of the wick.

. By constructing the flame-regulating tube F with the contractedportion f, a beveled shoulder f is formed which, when said tube islowered sufficiently abuts-against the top of the exterior wick-tube andprevents any further downward movement of the tube F. At the top of thecontracted portion of the flameregulating tube an annular flaring flangef is provided, which is adapted to abut firmly against the lower edge ofthe depending guard-flanged of the cap and to close the wick-space whenthe said tube is raised to its fullest height.

Formed in one side of the burner-base B is an inclined or spiral slot 9through which extends from the flame-regulating tube F a suitableoperating-handle G, whereby the tube may, by the lateral movement of thehandle, be axially rotated so as to lower or raise the same and permitthe wick to be lighted or to extinguish the flame, as the case may be.

The usual deflector H is supported above the burner by means of a postIt projecting axially from the fixed interior wick-tube, said post beingremovably anchored in a spiderframe or other suitable support h in theinterior of said tube. Theopen spider-frame permits the air passing upthrough the interior wick-tube to be supplied to the burner, and at thesame time alfords a support for the deflector H.

The parts being adjusted as shown in Fig. 1, the lamp may be lighted,the flame issuing from the exterior of the wick, and not from v the topedge thereof. The size of the flame is regulated by the position oftheflame-regulating tube, the latter being raised and low ered by meansof the operating arm G at its lower end. When it is desired toextinguish the flame, the flame-regulating tube is raised to its highestpoint, where, impinging" by its top flange against the'lower edge of theguardflange d it is stopped, the space between the two wick-tubes beingcompletely closed to prevent the rising of the smoke and noxious vaporswhich accompany the extinguishing of the flame of the ordinary lamp.

To renew the wick or to clean the-lamp, the deflector H is firstremoved, then the cap d df dt taken off the, interior wick-tube, andthen the burner-base B disconnected from the fount, said parts beingreplaced, after the wickthas been renewed or the lamp cleaned, in theinverse order named.

Having thus. described my invention, I claim as, new and desire. to,secure by Letters Paten.

1. The combinationwith the lampfount, of atstat-ionary interior wicktube extending through thefount, a stationary exterior-wick tube.-formingwith the interior tubea wick space, a, movable flame regulatingtubeprm jecting over the. exterior wick tu.be,and acap comprising-atubular portion adapted to bein: serted in the top of the interior wicktnbe,.an annular ring or top portion, and a, depending guard flangeonthe outer edge of said ring.

2. The combination with the, lamp fount, of a stationary interior wicktube extend. ing through the fount, a stationary exterior wick tubeforming with the interior tube a wick space, a movable flame regulatingtube mounted on the exterior wick tube and havinga contracted portionabove the latter, forming a shoulder at the base of said contracted 7portion, and aocap on theupper endoof the interior wick tube comprisinga tubular portion adapted to be inserted in the top of the interior wicktube, an annular ring or top portion and a depending guard flangeextending over the outer edge of the wick.

3. The combination with the lamp fount, of a stationary interior wicktube extending through the fount, a stationary exterior wick tubeforming with the interior tube a wick space, a movable flame regulatingtube mounted on the exterior wick tube, said flame regulating tubehaving a contracted portion above the latter and an outwardly flaringtop flange, and a cap on the upper end of the interior wick tubecomprising a, tubular portion adapted to, beinserted. in thetop, of theinterior wick tube, an annulanringontopportion and a dependi g gua dflange e tending over the outer edge of the wick.

4;. Thecombinationwiththelamp fountand the burner base thereon,providedwithanin- Qlined slot, of a stationary wick tube extending through the,fou;nt-,ra stationary exterior wick tube forming with the; interior tubea wick spacaa movable flame regulatingtnbe guided on and projecting overthe, exterior wick tube, an. operat ng. an le; projecting from the flameregulating tube and extending-through said slot,anda cap on the, upperendof the interior wicktube comprising an interior tubular portion andan, exterior de pending guard flange extending-over the wick.

In testimony that I claim the foregoing; as my invention IhaVe signed;my name in presence of two subscribing witnesses.
